I am simulating a water droplet impact surface under electrical field based on the interFoamEHD solver which designed by ivook.My model is 2D-Axisymmetric. I find that the charge density distribution is weird, there is some charge appearing above the droplet along the axis. I am puzzled by this problem. The charge density distribution is related to the velocity Magnitude.
I think the charge conversation equation is calculated for all computation field,both water and air. However, for water, it will get polarized and ohmic migration of charged ions. For air,it can be regarded as a perfect dielectric, there is no charge convection.Gauss law should be I think we should use different physical model for water and air. But can it be realized in openfoam. I am comfused by the interfoam solver. How does this sovler distinguish the phase1 and phase2? I am reading the twoPhaseMixture.H, incompressibleTwoPhaseMiture.H ,but still get stuck.Could you please give me some advices? Last edited by XinXin; October 31, 2019 at 07:51. |
